# [−][src]Function mynewt::kernel::os::os_cputime_timer_start

    pub unsafe extern "C" fn os_cputime_timer_start(
        timer: *mut hal_timer,
        cputime: u32
    ) -> c_int

Start a cputimer that will expire at 'cputime'. If cputime has already passed, the timer callback will still be called (at interrupt context).

NOTE: This must be called when the timer is stopped.

- `timer`: Pointer to timer to start. Cannot be NULL.
- `cputime`: The cputime at which the timer should expire.

Return: int 0 on success; EINVAL if timer already started or timer struct invalid

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
